Abstract
Objective To explore the main reasons of Andrographis paniculata seed dormancy,and find out a method of breaking the dormancy,improving the germination rate,and thus to provide the basis for standardized cultivation of Andrographis paniculata.Methods The Andrographis paniculata seed was pretreated by rubbing the seed coat,cutting the seed coat,warm or cold stratification,soaking into different concentrations of salicylic acid and different concentrations of potassium nitrate solution,and adding water-extraction of Andrographis seeds.Results Treatments of rubbing the seed coat,soaking in 0.5%-5% KNO3,high temperature stratification at 30 ℃ to 33 ℃ succeeded in promoting the germination,while the treatments of soaking in 0.1-5 mol/L salicylic acid,cold stratification at 4 ℃ and adding 0.01-0.2 g/mL water-extraction of Andrographis seeds inhibited the germination.Conclusion There are chemicals of inhibiting the germination and external cause and physiological dormancy in the Andrographis paniculata seed.
